Frequently asked questions

Is daylight saving time taken into account?

Yes. The converter uses your browser’s up-to-date time zone database, so DST changes are applied for each zone and date.

Why does a city show a different date?

When it is late in one zone it may already be the next day in another. The weekday is shown to make this clear.
